PATCHER SHUTDOWN
1. Open the electrical enclosure box and turn all toggle switches to the
OFF
position.
2. Remove unused asphalt and clean hopper floor with an environmental-friendly
asphalt release agent to prevent a build-up of asphalt that could result in heat loss
to the hopper contents. Asphalt build-up on the hopper floor will decrease the
useful life of the patcher and cause the burner to run excessively. The built-up
asphalt will act as an insulator and keep the material inside the hopper from heating
properly. Material may be kept warm overnight, but hopper floor should be cleared
as often as possible at the end of the day to extend the life of the patcher.
KEEPING HOT MIX OVERNIGHT
To keep hot mix asphalt overnight:
1) Move patcher to a well ventilated area.
2) Fill diesel fuel tank
3) Connect patcher battery to a battery charger that is plugged into building power having
a 120VAC ground fault circuit interrupt. Plug extension cord into building power
LAST
.
Use a heavy-duty UL approved extension cord.
4) Leave HOPPER toggle switch ON/UP and set automatic temperature controller setting to
180 degrees Fahrenheit. Patcher burner will cycle on and off throughout the night
keeping material at 180 degrees. If patcher has a RECYCLE toggle switch it should be
left in the DOWN/OFF position when keeping hot mix asphalt overnight.
5) Raise the hopper temperature controller to an application temperature in the range of 240
to 270 degrees Fahrenheit the next morning.
To keep cold mix asphalt overnight, turn off burner and turn on the next day.
Although material may be kept in the hopper overnight, as a general rule, the hopper floor
should be cleaned at the end of each workday.
3. Clean work area and shovels with an environmental-friendly asphalt release agent.
DANGER: Never us a flammable material to clean hopper because material could
ignite and cause serious injury or death.
4. Inspect tires, brakes, breakaway, lighting, attached options, etc. and report any problems or
concerns to a supervisor.
5. Fill the diesel fuel tank at the end of each day.
6. Inspect hydraulic hoses connecting the spool valve with the towing vehicle and report any
problems or concerns to a supervisor.
